Regardless of whether a backplane is present or not, the slim-line CDROM or DVD-CDR drive
is mated with an interposer card which provides the power and IO interconnects between the
drive, power supply and baseboard. The interposer card has three connectors; the first has 50
pins and is plugged directly into the drive connector. The connector has the following pinout.

The second connector has 4 pins and is cabled to the 2x3 pin power lead from the power
supply. The power cable for the drive is included in the SC1400UP in the form of a Y power
cable. Both ends of the Y cable are necessary when a slimline CD/DVD is used in conjunction
with a floppy installed in the hard drive bay. Both ends of this are identical and have the
following pinout.
